A) \[\frac{1}{2}\]
B) \[\frac{3}{4}\]
C) \[\frac{2}{3}\]
D) \[\frac{1}{4}\]
Correct Answer: A
Solution :
The figure shows free body diagram of the block. For equilibrium, along the plane \[\mu R+T\cos {{45}^{o}}=mg\sin {{45}^{o}}\] \[\mu R+T\frac{1}{\sqrt{2}}=\frac{mg}{\sqrt{2}}\] (i)You need to login to perform this action.
